Fresh lawsuit Fresh Trouble: A woman named Thalia Graves is suing Diddy claiming she’s had suicidal thoughts since Diddy and his head of security Joseph Sherman violently raped her

Diddy and a friend viciously raped a woman at the Bad Boy Records studio in New York City, and recorded the sexual abuse on video … at least according to a new lawsuit.

A woman named Thalia Graves is suing Diddy, claiming she’s had suicidal thoughts since Diddy and his head of security Joseph Sherman violently raped her back in

2001 … according to new legal docs obtained by TMZ.

In her suit, Graves claims she was 25 years old and dating one of Diddy’s employees when he lured her into a meeting with him and Sherman alone, where she says they sequestered her and gave her a drink “likely laced with a drug that eventually caused her briefly to lose consciousness.”

Graves claims she woke up to find herself bound and restrained … with Diddy and Sherman proceeding to brutally sexually abuse and violate her … mercilessly raping her anally and vaginally.

Diddy’s newest accuser claims she’s thought about killing herself and got extensive psychological treatment as a result of the alleged rape … and she says she never reported the incident out of fear that they will use power to ruin her life
